Most booth conversations never reach your CRM. Reps collect cards, write "hot lead," and by the time the thank-you email goes out, the context is gone and the prospect has moved on. B2Brain moves the follow-up onto the show floor. Snap a badge, speak a 15-second note, and send a calendar invite before the visitor leaves your booth. WORKS AT ANY EVENT, NO ORGANIZER SCANNER NEEDED B2Brain reads the name and company from a photo. It does not depend on the organizer's QR code, so it works at trade shows, conferences, roadshows, networking dinners and customer site visits. • Scan a badge or business card, even at an angle. • No badge or card? Upload a screenshot of their LinkedIn profile. • A group at the booth? Say the other visitors' full names in your note, and B2Brain adds and enriches them too. SPEAK YOUR NOTES. BOOK THE MEETING ON THE SPOT. • Tap the mic and talk while you look at the person. B2Brain transcribes it for you. • Say "let's meet next Thursday at 10:30," and B2Brain opens a calendar invite with the time, their email and a topic taken from your note. • If that slot is taken, B2Brain suggests free times. Works with Google and Microsoft calendars. • Booth rush? Keep scanning. Add notes later from the Recent tab. • Edit any note after you save it. KNOW WHO YOU ARE TALKING TO • Contact details are filled in for you: email, LinkedIn and phone number where available. • Each company shows recent account signals you can use to open the conversation. Teams can set their own signals. • See what a colleague already noted about the same person, at this show or an earlier one. KEEPS WORKING WHEN THE WI-FI DOES NOT • Scan, take notes and queue meeting invites with no signal, even in airplane mode. • Everything syncs on its own once you are back online with the app open. CLEAN DATA IN YOUR CRM • Save straight to HubSpot or Salesforce. B2Brain matches existing contacts by email, so it does not create duplicates. Notes attach to both the contact and the account. • Every lead is tagged with its event, so you can compare shows inside your CRM. • Another CRM? Export a CSV from the web dashboard at any time. FOR MARKETERS AND EVENT MANAGERS • A web dashboard shows every rep's scans and notes as they happen. Filter by event, date, rep or account. • The next working day, you get an Offline-to-Pipeline report: all leads, quality opportunities, meetings booked, your Leads-to-Meeting (LTM) rate, and a next best action for each lead. • Your data stays after the show, so you can track accounts and trends across every event you attend. FOR EXHIBITORS AND SALES TEAMS • Walk in with a target list. Book the meeting at the booth. Walk out with a report your CMO can use. • Stop paying the memory tax. Every conversation has its context attached, with the rep's name on it. "Snap a pic, add a quick voice note and save. Enriched data and context is quickly added, and I can refer back anytime." Jason Dumois, Hippo Video GET STARTED Your first event is free for up to 2 users. Sign in with Google or Microsoft to connect your calendar. If your company restricts Google or Microsoft OAuth based sign-in, your IT admin may need to approve B2Brain first.
